sharedevice_part# not working in batocera-boot.conf

[Hew-ux]

Issue: The part-specific external storage segregation as specified in the wiki is not working. It will default to using internal storage instead, as if the configuration were invalid.

Reproduction:

1. Have Batocera running on a device with two drives on it.
2. Correctly identify the UUID of the other drive with blkid, and ensure the folder structure is present.
3. Edit /boot/batocera-boot.conf to have the following:

sharedevice=DEVICES
sharedevice_part1=ROMS@<UUID here>:/path/to/roms

4. Batocera will fail to use this configuration.

Logs and info:
mountDevicesOrNetworkerr.txt
mountDevicesOrNetworklog.txt

These seem to be the exact same errors as seen in #6726 , this could be a duplicate issue, one that is affecting all external boot options.

I'm having the same issue. Internal is running on an ext4 NVME, while ROMS and BIOS I want accessed from an external ntfs drive (primarily because I need SAVES stored on the ext4 for some flatpak app compatibility).

It appears the potential cause was mentioned when the sharedevice=DEVICES feature was added (#5933 (comment)), where mount is used instead of batocera-mount (in v35 and beta v36: https://github.com/batocera-linux/batocera.linux/blob/36/board/batocera/fsoverlay/etc/init.d/S11share#L90).

I unfortunately can not submit a PR to fix, but am I correct in reading the wrong mount was used and potentially is why this feature does not work in my case?

Same issue here. My configuration:

sharedevice=DEVICES
# Default userdata partition but custom path
sharedevice_part1=SHARE@A442D9C142D997FE:/Games/Batocera
# SD card
sharedevice_part2=ROMS@03EF7FA94F1C5D39:/test

So the part1 is mounted successfully, but the part2 failed.

mountDevicesOrNetwork.err.txt
mountDevicesOrNetwork.log.txt

I hope there will be a solution soon.
